Got an annual bonus or sold an asset? Injecting that capital into your debt is a brilliant move. The Part Payment Calculator visually demonstrates the massive impact of lump-sum injections on your active loans.
Prepayment vs. Part Payment
While often used interchangeably, part payment specifically refers to making bulk lump-sum injections at specific intervals during the loan lifecycle. Because interest is calculated on the daily outstanding balance, executing a part payment immediately stops interest from compounding on that specific chunk of money forever.
The Impact Logic
When you make a part payment P_part, the new outstanding principal becomes P_new = P_current - P_part. The bank then recalculates your future interest based entirely on P_new.
Strategic Timing
The golden rule of part payments is: Do it as early in the loan tenure as possible. In the first 5 years of a 20-year home loan, up to 80% of your EMI is purely interest. A part payment made in Year 2 will save exponentially more money than the exact same part payment made in Year 15.
